Two Adhesive Questions

The first question is, what would be the best adhesive to put on the blue tape to prevent warping on large pieces?

The second question is, what adhesive works best for permanently gluing PLA parts together? Or gluing PLA to other materials?

    Personally my prints stick hard to the tape if I wipe it down with alcohol first. But then you have the problem of having the tape peel off the platform and then you're back at square one again. I really need to build myself a heated bed one of these days...

    As for gluing parts the only thing I've tried is "Super" (yeah right..) glue and it works decent but not great. It will also discolour the plastic a bit.

    Yeah, I tried super glue, too. It doesn't work well at all. I might go buy some Weldbond. It's supposed to glue just about anything to anything.

    I've personally had fantastic results with superglue (cyanoacrylate). I've glued many different PLA models together with it and they're as strong as if it was printed as one piece. I've not had any glue joints with superglue ever come apart on me.

    I've also had success with standard plastic model glue (used for building polystyrene aeroplane / car models, etc.) such as this:

    it's very slow to cure and smells horrible though, so I usually stick with regular superglue.

    Cheers,

    Troy.

    Which brand of super glue are you using? I tried Locktite brand at it wouldn't bond right.

    Hi Bill,

    Try Dichloromethane (liquid solvent cement) it has a water like consistency. It's what I use as a professional model maker.

    Regards

    Mark

      • Here it is. The new UltiMaker S7
        The UltiMaker S7 is built on the success of the UltiMaker S5 and its design decisions were heavily based on feedback from customers.
         
         
        So what’s new?
        The obvious change is the S7’s height. It now includes an integrated Air Manager. This filters the exhaust air of every print and also improves build temperature stability. To further enclose the build chamber the S7 only has one magnetically latched door.
         
        The build stack has also been completely redesigned. A PEI-coated flexible steel build plate makes a big difference to productivity. Not only do you not need tools to pop a printed part off. But we also don’t recommend using or adhesion structures for UltiMaker materials (except PC, because...it’s PC). Along with that, 4 pins and 25 magnets make it easy to replace the flex plate perfectly – even with one hand.
         
        The re-engineered print head has an inductive sensor which reduces noise when probing the build plate. This effectively makes it much harder to not achieve a perfect first layer, improving overall print success. We also reversed the front fan direction (fewer plastic hairs, less maintenance), made the print core door magnets stronger, and add a sensor that helps avoid flooding.
         

         
        The UltiMaker S7 also includes quality of life improvements:
        Reliable bed tilt compensation (no more thumbscrews) 2.4 and 5 GHz Wi-Fi A 1080p camera (mounted higher for a better view) Compatibility with 280+ Marketplace materials Compatibility with S5 project files (no reslicing needed) And a whole lot more  
        Curious to see the S7 in action?
        We’re hosting a free tech demo on February 7.
        It will be live and you can ask any questions to our CTO, Miguel Calvo.

      • UltiMaker Cura 5.3.0-Alpha 🎄 Tree Support Spotlight 🎄
        Are you a fan of tree support, but dislike the removal process and the amount of filament it uses? Then we would like to invite you to try this special release of UltiMaker Cura. Brought to you by our special community contributor @thomasrahm
         
        We generated a special version of Cura 5.2 called 5.3.0 Alpha + Xmas. The only changes we introduced compared to UltiMaker Cura 5.2.1 are those which are needed for the new supports. So keep in mind, this is not a sneak peek for Cura 5.3 (there are some really cool new features coming up) but a spotlight release highlighting this new version of tree supports.
